Will Methadone Make Me Fail a Drug Test?

Jul 22, Can Poppy Seeds Create a Positive Methadone Drug Test? According to the U.S. Anti-Doping Agency, poppy seeds can trigger positive results in a test for morphine. Poppy seeds can become coated by or absorb opium extract during harvest. About 12 percent of opium consists of morphine, an opioid tested in many drug screenings. May 25, If you can, buy a home drug testing kit and take it just to see if the home kit shows you positive for any opiates. Subs were specially designed not to test positive for opiates, so dr can tell if patients are relapsing. If your home result still has you testing positive, have dr check for metabolic disorder or other underlying problem.

I take Benedryl every night for sleep and ibuprofen daily pretty much. I have a few other prescriptions meds, but not methadone! Has 44 years experience. How to encourage workplace diversity 1, I immediately sent him a message and told him to make sure he had makke listed on my what is an it technical specialist med list and notation of the date we spoke about it.

Didn't they remove the 'purp drank' out of benedryl kids were taking it for? I have no idea honestly.

I just read a lot of people saying if they were in monitoring programs that Benedryl was banned. Feb 8. The screen came back completely fine. Just a heads up if this ever happens to anybody methaeone in the future. They had to send it to a lab to be tested what can make you test positive for methadone they confirmed that I in fact did not have methadone in my system.

It took weeks though and it was terrifying. Davey Do. Specializes in around 25 years psych, 10 years medical. Has 42 years experience. That was a very kind move on your methaxone to come back and give us an update. It is good that you love your job! As a side note, back in the 80's Motrin would give a false positive on a UDS for pot. It's strange to think that, in those days, both Benadryl and Motrin were prescription meds!

Feb 11, These Cross reaction guides list medications that can cause either non-reaction (have no effect) or are reactive (you fail) to specific drugs, medications, vitamins, herbs or foods. As an example, if you take Advil PM, which some Cross Reactive Guides say is reactive to a Methadone drug test, you could test positive for Methadone use. Jun 10, Drugs that can cause false positives. 1) Dextromethorphan. Dextromethorphan is an active ingredient in Robitussin, Delsym, and other over-the-counter cough suppressants. If youve taken a 2) Diltiazem. 3) Diphenhydramine. 4) Metformin. 5) Pseudoephedrine. Mar 07, All the following have been reported to cause methadone false-positives: Chlorpromazine; Clomipramine; Doxylamine; Diphenhydramine; Quetiapine; Thioridazine; Verapamil; Verapamil has extensive published evidence that it can be responsible for false-positive methadone tests. One study, published in Clinical Chemistry, notes that it is likely the most common .

In the context of methadone maintenance programs, immunochemical detection of methadone in urine has evolved, with rapid and sensitive techniques gaining impact in clinical laboratories because of their cost-effectiveness and suitability for automation 1. However, immunochemical methods may lack the specificity necessary for accurate measurement.

We report spurious methadone results encountered in a psychiatric hospital. The test is used in the qualitative mode, with a methadone concentration exceeding 0. This technology is known for its steep doseresponse curve around the cutoff of the assay 1. In its first formulation, the reagent included a polyclonal antibody that remained free in solution and captured either methadone or a methadone multivalent conjugate coupled on microparticles.

In September , Roche Diagnostics switched from the polyclonal antibody to a monoclonal antibody and modified the original KIMS technology by coupling the antibody to the microparticles and keeping the multivalent drug conjugate in solution. This second-generation inhibition assay was expected to improve the sensitivity and specificity of the test 2.

Soon after this change, some clinicians contacted the laboratory about a mismatch between the clinical information and the methadone detection result.

We therefore performed additional tests on these samples, using another immunoassay for methadone Emit II Plus Methadone; Dade Behring , a gas chromatography assay, and an assay for the methadone metabolite ethylene dimethyl diphenyl pyrrolidine EDDP; Microgenics.

The limits of detection of these assays are 0. This problem of false positives concerned 8. These psychotropic molecules with a phenothiazine structure are widely prescribed in our hospital and are excreted in urine. In 3 cases, no therapy except olanzapine was recorded. In our experience, only samples from patients treated with cyamemazine or levomepromazine give false-positive results. Nevertheless, in 3 olanzapine-treated cases, no therapy could explain the false-positive result because olanzapine is unlikely to interfere.

In these 3 cases, we cannot exclude that a cross-reacting substance may have been administered before the hospitalization. Some metabolites of the psychotropic drugs tested could also induce a cross-reactivityrelated artifact in these patients.

Some false-positive results for methadone have already been reported with other techniques and were attributable to metabolites of verapamil 4 , diphenhydramine 5 , or doxylamine 6.

In our patients, these compounds are not an issue of concern. The cross-reactivity related to psychotropic drugs or their metabolites represents a drawback of the new Roche assay: psychotropic therapy may be used in a patient on methadone maintenance therapy because relationships frequently exist between mental illness and substance abuse disorders 7.

Methadone and EDDP may well be absent in the urine initially, but will appear when the dosage has been increased to a sufficient amount. Thus, methadone or EDDP in urine can serve as a guide to appropriate dosage 8 , and interference such as described above will hinder correct dosage adjustment.

Adulteration is also a major problem in methadone maintenance, where patients have strong incentives to cheat 9. Therefore, either another methadone assay or detection of the methadone metabolite EDDP should be preferred in a methadone maintenance program. Roche Diagnostics has now included a notice concerning the cyamemazine cross-reactivity in the reagent information.

Although the new assay format provides significant analytical improvement for detection of other drugs 2 , as far as methadone testing is concerned, the monoclonal antibody used is a source of error, particularly for cases in which drug abuse is combined with a clinical psychiatric condition. We are grateful to Catherine Boyer and Edith Mouchet for expert technical assistance. We thank Roche Diagnostics for providing us with reagents.
